0.Product Description

1.Notes on Operation:

RPB-1600 is MEAN WELL's new generation intelligent battery charger with high power density.

Different battery brands and types (lead acid batteries, such as flooded, Gel, AGM, and so on, or

lithium-ion batteries, such as lithium iron, lithium manganese, and so on) may require different

charging curves and protection mechanisms for batteries. RPB-1600 is able to be accommodated

through the communication interface; parameters, such as charge voltage, charge current and taper

current, can be adjusted and the protection mechanisms for batteries can also be cancelled.

◎ The charger must be installed in a dry and well ventilated area. It should not be exposed to rain

or snow.

◎ The cables between charger and battery should be kept as short as possible to prevent excessive

voltage drop. Too much voltage drop will lead to longer charging period.

◎ Please make sure charging voltage and current meet battery specification.

◎ While charging batteries in series do not mix old and new batteries in the same connection.,

◎ When connecting or disconnecting wires, please ensure the charger is OFF.

◎ Under normal operating conditions, a 5 years warranty is offered for RPB-1600. If failure results

from improper operation, the warranty will not apply to the defective units.

Installation Procedure:

Please make sure the charger is OFF before connecting the battery to the output terminal. Choose a

cable with suitable wire gauge according to the charging current to connect between the charger and

the battery. Battery polarity must be connected correctly:Terminal(+) to Battery(+); Terminal(-) to

Battery(-), and take notice that the positive and negative ends are not shorted.

Description

SW1 is the selector of terminal resistor that is designed for DA/DB signals and parallel control function.

At the beginning stage of operation, the charger provides the largest current to charge the batteries,

the LED indicator will lighten in orange. After a period of time (probably a couple of hours, based on

the capacity of the batteries), the charging current will decrease gradually. When the output current

reduces to 10% of its maximum value, the charger will go into “float” mode, the LED indicator will

turn to green. The relationship between charging current and charging voltage for each operation

stage is shown in the curves below:

Explanation for 3 stage charge curve

(0) Initial stage (battery analysis): Check battery voltage level to see whether there is a battery

connected.

(1) Stage 1 (constant current): A constant current is provided so that the battery can be quickly

charged to 2.4V per cell.

(2) Stage 2 (constant voltage): A constant voltage of 2.4V per cell is provided until the charging

current gradually reduces to 10%.

(3) Stage 3 (float) The output voltage switches to the float voltage, making it 2.3V per cell to keep the:

battery fully charged.

Page 7: RPB-1600 Instruction Manual - Sunpower UK...Each RPB-1600 unit should have their unique and own device address to communicate over the PMbus. This 7-bit address is defined as follows:

8.PMBus Communication Interface

RPB-1600 is compliant with PMBus Rev.1.1, the maximum communication speed is 100KHz and it

has the capability of identifying up to 8 addressed units.

◎ Each RPB-1600 unit should have their unique and own device address to communicate over the

PMbus. This 7-bit address is defined as follows:

1

MSB

0 0 0 A2 A1 A0

LSB

A0-A2 allow users to designate the address for each RPB-1600 unit; these three bits are defined

through PIN7 (A0), PIN8 (A1) and PIN9 (A2) on CN1. There are up to 8 different addresses are

available to be assigned. When connecting one of these pins, for example, PIN8, with PIN14

(-V(Signal)), the corresponding bit, A1, is set to logic “0”; when it is kept open, for example, PIN7, the

corresponding bit, A0, is set to logic “1”. Please refer to Figure 8-1(left) for the detailed setup advice.

◎ The charging operation can be determined by the setup over D0, PIN10 on CN1. When D0 is logic

“0”, connecting PIN10 with PIN14(-V(Signal)), RPB-1600 follows a built charging curve to charge the

batteries; when D0 is logic “1”, PIN10 kept open, the charging operation is completely defined by the

control over PMBus, PV/PC or SVR. Please refer to Figure 8-2(right).

Page 8: RPB-1600 Instruction Manual - Sunpower UK...Each RPB-1600 unit should have their unique and own device address to communicate over the PMbus. This 7-bit address is defined as follows:

NOTE: When operating in this mode, PMBus commands B0h/B1h…B8h can be set but there will

be no response whereas other PMBus commands and functions work normally.

PMBus, PV/PC or SVR Functions

Users are able to fully control and design the entire charging behavior, without the charging curve, by

one of the following means- PMBus command, PV/PC function or SVR adjustment. The operating

priority is, PMBus > PV/PC > SVR.

6

Charging Curve

When it is opted for charging curve, D0 set to 0, charging curve function is enabled with additional

PMBus commands. There are 4 built-in charging curves, “default” curve, one pre-defined curve for “gel

battery”, one pre-defined curve for “flooded battery” and one pre-defined curve for “AGM battery”.

Each curve can be selected by Command B4h CURVE_CONFIG.

In addition users are able to customize their own charge curves which will be stored to “default” after, ,

modification Vboost can be set by Command B1h CURVE VBST VFloat can be set by Command. _ ;

B2h CURVE VFLOAT Charge current level of stage1 can be set by Command B0h CURVE ICHG_ ; _ ;

Taper current level from stage2 to stage3 can be set by Command B3h CURVE ITAPER Please_ .

refer to the following PMBus Command List in table 8 2 for detailed information on commands and-

parameters.

NOTE: 1. The updated charging parameters is saved into EEPROM. The updated charging curve

takes effect after RPB-1600 is restarted.

2. When charging curve is enabled, the following commands will be invalid while other PMBus

commands are effective: Command 01h OPERATION (regarding Remote ON-OFF function),

Command 22h VOUT_TRIM (regarding Output voltage programming function) and

Command 46h IOUT_OC_FAULT_LIMIT (regarding Output current programming function).

Select suitable wire guage based on rated charging current. Refer to the following table for

minimum wire gauge. It is highly recommend using RED wire for (+) connection and BLACK wire

for (-) connection

The main drawback is it may take longer to fully charge the battery.

2.If you're unsure about max allowable charging current of your battery, please refer to the

battery's technical specification or consult its manufacturer.

1 .3 Troubleshooting

If you are unable to clarify the problem you are facing, please contact MEAN WELL or any of

our distributors for repair service.

Failure State

Unable to chargethe battery

LED indicator doesnot turn Green aftera long chargingperiod

Possible Cause

Make sure input source isbetween 90~264VAC

Replace with a new battery

Replace with suitable wire gauge

Input voltage too low

Battery is over lifetime or damaged

Output cables are too thin

2.Batteries in parallel

When 2 batteries are connected in parallel, voltage remains the same and the capacity (Ah) doubles.

For example, 2 x 12V 100Ah batteries connected in parallel = 12V 200Ah.
